IMPROVED SELF-'EN'ILATING SAFETY-CAN FOR FILLING .AND DISCHARG-ING-'HYDROCARBQN-APPARATUS.

The Schedule :referred to in these Lettera Patent and making part of theBarneproveniente.

The invention, in the construction of my can, consists in thearrangement of a tube therewith, in such manner that one ot' its endswill be iu direct communication with the opening through which thevessel is filled with the tluid, while its other end is in direct`communication with the, opening through which the tlnid is dischargedii'om the vessel; that is to say, the openings ot' said tube maintainrelatively such a position with respect to the openings of the can, asthat the'iiuid passing into or outot' the vessel, shall be greatlyliastened in its passage, by reason of 'the current of air and a portionot' the fluid passing into the vessel, or'therefrom, through the tube,whereby I am enabled to lill the vessel from an air-tight reservoir, anddistribute thei'luidto another .air-tight reservoir, thus producing acirculation, and without any communication whatever with the atmosphereoutside of the vessel.

In the accompanying drawings- A represents the safetyVentilating-vessel, made of tin and zinc combined, for the purpose ofpreventing oxidization.

A single tube, B, is connected to the vessel, the upper end of which iscontiguous to and in direct communication with the opening through whichthe can is tlled, while its lower end occupies a'position in directcommunication with the opening through which the luid isdischarged fromthevessel.

The ends of the ,tube projecting directly into the' ingress andegress-openings ofthe vessel, the eiiect of this arrangement is toproduce a perfect circulation of the `air and tluid from into andthrough the air-tight vessel or vessels, which is accomplished in a muchless time than it'can be done without the tube, and with perfect safetyto health, life, and property. f

The ingress-opening is provided with a faucet or stop-cock, C, to whichthe .pipe leading to the reservoir is secured, and the egress-opening islikewise provided with a faucet or stop-c0ck,'C, to which the pipe D,leading to the'arburetter, is secured. y

lhen the vessel is being filled, the lower stop-cock is closed, but iuusing it as an intermediate circulating-vessel, both of its stop-cocksare opened, and for this purpose is very usefuLfor conducting gas,acids, 1

and explosive fluids from one air-tight vessel toan- 1. Theventilating-tube Barranged within the ves-v v sel A, having its ends indirect communication with the ingress and egress-openings thereof', vsoas to facilitate the circulation of the ail-'and iluid therein, whetherin filling or discharging from or into air-tight vessels, as described.

2. The vessel' A, constructed as described, to be used as anintermediate circulating-vessel, in drawing from one airtight vessel tofill another, substantially a's described.

3. The combination of the vessel A, the circulatingf tube B, and thestop-cocksor faucets (ll C, constructed, arranged, and operating asdescribed.
